Final answer:
To calculate the number of atoms in 0.538 mol of 13C, multiply the number of moles by Avogadro's number, which is approximately 6.022 × 10^23 atoms/mol. The number of atoms in 0.538 mol of 13C is approximately 3.24 x 10^23 atoms.
Step-by-step explanation:
To calculate the number of atoms in 0.538 mol of 13C, we can use Avogadro's number, which is approximately 6.022 × 1023 atoms/mol. Multiply the number of moles by Avogadro's number:
0.538 mol x 6.022 × 1023 atoms/mol = 3.24 x 1023 atoms
